AI helps Stanford scientists discover a “natural Ozempic” with a surprising advantage

Stanford researchers have discovered an AI-identified natural molecule that dramatically suppresses appetite and promotes fat loss in animals, potentially offering an Ozempic-like weight-loss treatment without common digestive side effects or significant muscle loss. Called BRP, the molecule reduced food intake by up to 50% and targets a different brain pathway, raising hopes for a more precise obesity treatment if future human trials prove successful.

Testing Einstein's laws from the bottom of the Mediterranean Sea

Are the laws of physics truly the same everywhere in the universe? This fundamental principle, known as Lorentz invariance, lies at the heart of Einstein's theory of relativity. Yet some theories that seek to reconcile gravity with quantum physics suggest that it might not always hold. To investigate this possibility, researchers from the international KM3NeT collaboration analyzed 5,828 atmospheric neutrino candidate events detected by KM3NeT/ORCA, a neutrino telescope located deep in the Mediterranean Sea.

Loophole listing keeps seafood qualifying as critically endangered on the menu

One of Australia's most dangerously overfished species, redfish (Centroberyx affinis), will continue to be served on our dinner tables following its latest listing as "conservation dependent." The classification is a loophole allowing species that qualify for critically endangered listings and protections to instead be killed and sold for seafood.

Gene editing could replace a lifetime of medication, but there's a catch

A single gene-editing treatment could someday protect against heart disease, high cholesterol, and other common conditions for decades, potentially replacing lifelong medications. But scientists warn that permanently altering genes introduces risks that could take years to emerge, making long-term safety a critical challenge.

Scientists trick cancer cells into making the drugs that kill them

Scientists have developed a promising new cancer-fighting strategy that uses carbon monoxide naturally produced by tumor cells to manufacture powerful drugs inside the cancer cells themselves. Early laboratory experiments suggest the technique could selectively attack cancer while sparing healthy cells, potentially paving the way for safer chemotherapy alternatives.

Researchers develop sensors for continuous corn growth monitoring

When is the best time to apply nitrogen? What plant response was there to fertilizer or any number of other treatments? There is a general answer to those questions now, but what if plant breeders and agronomists could download data from continuously monitored cornstalks and ears to develop specific answers for those questions?

How anxiety over climate change affects college students

College undergraduates are anxious about climate change, with many feeling powerless and frustrated about Earth's future, yet resources to help students cope are in short supply, according to new interdisciplinary University of Utah research. The sentiment isn't limited to students studying the environment.

A hidden star is plowing through Betelgeuse’s atmosphere, new evidence suggests

Something mysterious is disturbing Betelgeuse, and astronomers believe they have identified the culprit: a hidden companion star called Siwarha. New radio observations reveal that the smaller star may be plowing through Betelgeuse’s enormous atmosphere, creating disturbances that subtly stretch and distort the red supergiant’s shape.

One in 15 adults has experienced AI-generated image-based abuse, study finds

Around one in 15 adults has experienced AI-generated image-based abuse, according to a new study. The general-population survey of more than 7,200 adults in the United States, the United Kingdom and Australia found 7% had experienced at least one form of AI-generated image-based abuse since turning 18.

Lab-grown neurons retain features of embryonic development

Scientists from Skoltech, together with colleagues from the Kharkevich Institute for Information Transmission Problems of the Russian Academy of Sciences, Lomonosov Moscow State University and other organizations, conducted a comparative study of the 3D genome organization in neurons derived from induced pluripotent stem cells and in neurons of the adult human brain. The authors collected and processed more than 300 3D genome maps covering 62 human samples and 34 mouse samples, including data on embryonic stem cells, induced pluripotent stem cells, neural progenitors, fetal and postmortem neurons, as well as neurons differentiated in vitro.

Digitalization front-runners are more vulnerable to cyberattacks

For many business leaders, digitalization is associated with promises of greater efficiency and productivity. However, a new study by professor of accounting Jukka Sihvonen from the University of Vaasa, Finland, suggests that increasing digitalization may also raise a company's risk of falling victim to a successful cyberattack. The study has been published in the journal British Journal of Management.

Kids who eat more ultra-processed foods show a troubling brain response

A new study suggests that ultra-processed foods may influence children's developing brains in ways that encourage weight gain. Researchers from USC studied 46 children ages 7 to 10 and found that those who ate more ultra-processed foods showed stronger activity in the brain's reward system when viewing tempting foods like cookies and French fries. These heightened brain responses were linked to greater increases in body fat and body mass index (BMI) one year later, suggesting that the brain's sensitivity to food cues may help explain why ultra-processed diets are associated with obesity.

Study maps Nelore cattle microbiota to reduce methane emissions

Researchers at the Brazilian Agricultural Research Corporation (EMBRAPA) are studying the relationship between the genetics of Nelore cattle and the microorganisms in their guts (microbiota). Nelore cattle are the most widely raised beef breed in Brazil. The goal is to develop strategies that reduce emissions of methane—a major greenhouse gas—and improve the animals' feed efficiency.

North Atlantic's 'cold blob' may contain climate nuance

Climate observers have long tied the strength of a major ocean current to water temperatures in the so-called "cold blob" in the North Atlantic Ocean. The 965,000-square-mile (2.5 million square kilometers) area south and southeast of Greenland cooled by as much as 1.8 degrees Fahrenheit over the past century as other ocean waters warmed.

US midterm elections: Younger politicians could strengthen trust in democracy

It's no secret that American politics is dominated by older politicians. When 81-year-old Joe Biden withdrew from the 2024 presidential race amid concerns about his age, it was the then-78-year-old Donald Trump who ultimately entered the White House. The median age in the House of Representatives and the Senate was 58 and 65, respectively, while the average American was just 39 years old.
